EPA Releases Clean Air Rules

In response to a court deadline, today the U.S. Environmental Protection Agency (EPA) proposed the first-ever national standards for mercury, arsenic and other toxic air pollution from power plants. The new power plant mercury and air toxics standards – which eliminate 20 years of uncertainty across industry – would require many power plants to install widely available, proven pollution control technologies to cut harmful emissions of mercury, arsenic, chromium, nickel and acid gases, while preventing as many as 17,000 premature deaths and 11,000 heart attacks a year. The new proposed standards would also provide particular health benefits for children, preventing 120,000 cases of childhood asthma symptoms and about 11,000 fewer cases of acute bronchitis among children each year. The proposed standards would also avert more than 12,000 emergency room visits and hospital admissions and 850,000 fewer days of work missed due to illness. 

Toxic air pollutants like mercury from coal- and oil-fired power plants have been shown to cause neurological damage, including lower IQ, in children exposed in the womb and during early development. The standards also address emissions of other toxic metals linked with cancer such as arsenic, chromium and nickel. Mercury and many of the other toxic pollutants also damage the environment and pollute our nation's lakes, streams, and fish. In addition, cutting these toxic pollutants also reduces fine particle pollution, which causes premature death, heart disease, workdays lost to illness and asthma. 

Power plants are the largest remaining source of several toxic air pollutants – responsible for half of mercury and more than half of acid gas emissions in the United States. In the power sector alone, coal-fired power plants are responsible for 99 percent of mercury emissions. 

The proposed standards also ensure that public health and economic benefits far outweigh costs of implementation. EPA estimates that for every dollar spent to reduce pollution from power plants, the American public and American businesses will see up to $13 in health and economic benefits. The total health and economic benefits of this standard are estimated to be as much as $140 billion annually.
